Moving 5/6 year old clown to new tank. Possible to add a juvenile?

[Townes_Van_Camp]

I have a 5/6 year old black and white clown in a 14 gallon AIO. She shared the tank peacefully with a blenny, who jumped during a hurricane, for 4.5 years.

I am moving her into a new nano. A 25 gal lagoon. If I added a new juvenile clown ahead of her a few days, What do you place my odds of being successful keeping them together are?

If this is a terrible idea I want to know before I attempt it. I'd prefer not to buy a fish and have it battered.

I appreciate the help.

She is an Ocellaris and should readily accept a new mate, easy without much trauma, as long as you don’t add another female.

Thank you for the response. Much appreciated.
